Question

I’ve used arrays in other languages (Python, MATLAB/Octave, C, Visual Basic, BASIC), but I haven’t figured out how to use them in Android.

For example, how would I modify the Hello World program at World program at http://developer.android.com/resources/tutorials/hello-world.html to replace “Hello, Android” with the name of a TV show denoted by an index number (tvshow[0], tvshow[1], etc.)? Let’s name the array tvshow, and the four values in the array are “Route 66”, “The Twilight Zone”, “Magnum P.I.”, and “MASH”.

What method(s) can I use to accomplish this?

Answer 1

There is also ArrayList . So all you have to do to add is call the add method and to read you use the get method.

ArrayList <String> myArrayList = new ArrayList<String>();
//this is how you add the elements you want to.
myArrayList.add("Route 66");
myArrayList.add("The Twitlight Zone");
myArrayList.add("Magnum");
myArrayList.add("P.I.");
myArrayList.add("Mash");

and to read the element you want:

String tvShow= myArrayList.get(2);

The advantage over a normal array (i.e. the one that android developer mentioned) is that you dont need to define an array size and you can add new elements in case the tv shows you have aument by just calling the add method.
